Answer:
[tex]a=4.1[/tex]
Step-by-step explanation:
The Law of Cosines is given as:
[tex]a^2=c^2+b^2-2cb\cos A[/tex].
Plugging in given values, we get:
[tex]a^2=4^2+2^2-2\cdot 4 \cdot 2\cos 78^{\circ},\\a^2=16+4-16\cos 78^{\circ},\\a^2\approx \sqrt{16.673},\\a\approx \fbox{$4.1$}[/tex].

Answer:
A. m<R, m<S, m<Q
Step-by-step explanation:
In a triangle, the length of each side determines the size of the angle opposite it. Thus, the longer the side, the bigger the size of the angle opposite it. The shorter the side, the smaller the size of the angle opposite it.
In ∆QRS, we have the following:
✔️The longest side is RS = 16. <Q is opposite to RS, therefore <Q is the largest angle.
✔️The medium side is QR = 15. <S is opposite to QR, therefore <S is the medium angle.
✔️The shortest side is SQ = 9. <R is opposite to SQ, therefore <R is the smallest angle.
From smallest to the largest we would have:
m<R, m<S, m<Q

The angle of depression between the top of a 100-foot cliff and a ship approaching the shore is 37. What is the approximate distance, d, between the bottom of the cliff and the ship?
Answer:
76 feet
Step-by-step explanation:
let 'd' = distance from bottom of cliff and ship
sin 37 = sin 53
d 100
0.61 = 0.8
d 100
cross-multiply: 61 = .8d
d = 76
I assumed the bottom of the cliff and the shore formed a 90 degree angle - which leaves the 37° angle and a 53° angle

Ashley owns 14 acres of land which she rents to a Timber grower for $3131 per acre per year. Her property taxes are $882 per acre per year. How much profit does she make on the land each year?
A. $56,182
B. $42,952
C. $31,486
D. $44,716
Answer:
A. $56,182
Step-by-step explanation:
$3131 x 14= $43834
$882 x 14= $12348
$43834 + $12348= $56,182
$56,182 x 1= $56,182

Question 10 of 10
Which of the following is an x-intercept of the function, f(x) = x2 -5x2 - 8x +48
?
A. -4
o
B. 4
C. -2
O
D. 2
Answer:
Option B: 4
Step-by-step explanation:
From the image, the correct function is;
f(x) = x³ -5x² - 8x + 48
Now, the x-intercept occurs when y = 0.
Thus;
x³ - 5x² - 8x + 48 = 0
So we are looking for values of x that will make y = 0.
Let's try the options;
Let's try x = -4;
(-4)³ - 5(-4)² - 8(-4) + 48 = -64 - 80 + 32 + 48 = -64 ≠ 0
So, x = -4 is not an x - intercept
Let's try x = 4;
(4)³ - 5(4)² - 8(4) + 48 = 64 - 80 - 32 + 48 = 0
So,x = 4 is an x-intercept
Let's try x = - 2;
(-2)³ - 5(-2)² - 8(-2) + 48 = -8 - 20 + 16 + 48 = 36 ≠ 0.
So, x = -2 is not an x-intercept.
Let's try x = 2;
(2)³ - 5(2)² - 8(2) + 48 = 8 - 20 - 16 + 48 = 20 ≠ 0
So, x = 2 is not an x-intercept
Roberto is going to the zoo! The entrance fee is $25 and each souvenir costs $3.75. He
has $40. Roberto thinks that this inequality could be use to find the number of souvenirs
he can purchase. Is he correct?
3.755 + 25 < 40
No the inequality symbol should be greater than or equal to
No it should be minus 25
No the letters should be next to the 25
yes this is correct
Answer:
yes this is correct
Step-by-step explanation:
Josie packed unit cubes into a prism, as shown. Which statement about the volume of the box is true?
Also so, the answer to this is; The volume of the prism is less than 72 cubic units.
Why is this the answer?
The actually cubic units for that is actually 54 cube units which if you think is; 54 < 72
So I hope this helps. I wasn´t able to see the image but according to what I know, I think it is in one of the imagine math or something else lessons. If what im telling has nothing to do with your question, I am sorry and- I guess thats that. I really hope this helps. Bye!! ^m^

the mass of earth is approximately 5.9x10^24 kg, and the mass of venus is approximately 4.9x10^24 kg. find their combined mass
Answer:
28.91×10^48
hope it helps.
Because they both have the same exponent, just add the numbers together:
5.9 + 4.9 = 10.8
So now you have:
5.9 x 10^24 + 4.9 x 10^24 = 10.8 x 10^24
A scientific number can only have 1 number to the left of the decimal, so you need to move the decimal one place to the left. When you move the decimal to the left you add to the exponent.
The answer is: 1.08 x 10^25

Ginger mows
3/4 acre in 1 3/4 hours. What is her unit rate of acres mowed per hour?
9514 1404 393
Answer:
3/7 acres per hour
Step-by-step explanation:
To find acres mowed per hour, divide acres mowed by hours:
(3/4 ac)/(1 3/4 h) = (3/4)/(7/4) ac/h = 3/7 ac/h
Ginger's unit rate is 3/7 acres per hour.
Answer: 3/7!

8. r=
d =
C=78.8 ft
Answer: The radius is 12.54 feet, and the diameter is 25.08 feet.
Explanation: By applying the circumference into the equation r = [tex]\frac{C}{2\pi }[/tex], we get r = [tex]\frac{78.8}{2\pi }[/tex]which simplifies the radius. And since radius is half of diameter, we multiply by 2 to get the diameter as well to solve the other blank in the problem.
Hope this helps! :D
